DUST CGLLECTOR.

Application filed Asril 30, 1924;. Fjerial lio. 710,095.

To all whom it may concern it known that 1, Homer A. WALKER, J12, a citizen of the United States, and a resident of l'v'laplewocd, in the county of Essex and State of New Jersey, have invented cerein ne and useful Improvements in Dust Collectors, of which the following is a specification.

This invention relates to a dust collector for use with coal burning furnaces, etc, and comprises an improved device of this class adapted to be used in connection with any device to receive ashes when removed front the furnace and to permit the handling of ashes without the usual accoml. H n l 13! I 1 r-w pannnent of dust 1n the furnace 100111. .1 he device herein is, without change of any kind,adapted for use with any type of furnace or range using coal as fuel.

1-111 important object of the invention is the provision of a sanitary, selt-contained device which is not permanently attached to the furnace or ash receptacle but which may be easily positioned for use in connection therewith without making any change in either.

A feature of the invention relates to the construction of the hood which is adapted to effect circulation of dust therein tocollest the dust and expedite itsremoval there from by utilization of the furnace draft.

Other features relate to the construction of the dust-collecting hood which adapt it for use with any furnace or ash receptacle, without change or addition thereto, or for changing the position of the ash receptacle relatively to the furnace.

These and other features of the invention not hereinhefore referred to will be hereinafter described and claimed and are illustrated in the accompanying drawing, in which:

Figure 1 is an elevation, partly in section, of an ash receptacle provided with a dust collector embodying the invention, it being shown in operative relation to a coal-burninc furnace, and V Fig. 2 is a section thereof taken on the line 22, Fig. 1.

Referring to the drawings, 2 designates a furnace in conventional form adapted for burning coal, the coaling door of which is designated by 3 and the cooling opening by 1, while the ash-pit door and opening are designated by 5 and 6, respectively. I have shown an ash receptacle or can 'F, upon which is positicned a collecting hood 8, said hood being formed with a flange 9 at the bottom thereof: to permit the hood to he need with cans of dillerent dian'ieters. Hurdles 10 are provided on the hood 8 to facilitate the renioval of d hood from the can for ung, etc. At 11 is shown an 'openlng in we hood 8 adapted to permit whose other into the co 11g opening; 1- of the furnace.

The pip shown herein as comprising the elbows 17 and 1S and an interniediaae straight length It will be seen that by this arrangement of the pipes the ash receptncie may he placed on either side of the furnace, the pipe as a whole being reversible 1n position to meet the requirements of this change of position. 7

T he openings 11 and 12% are located, preferably, near the lower edge of the hood 8 in order hat the dust rising from the ashes deposited in the receptacle may be caused to'circ late or col ect in the relatively large upper portion of said hood, partly falling baclr into the receptacle? and partly re moved by the draft through the pipe 17 19-18 and carried to the furnace opening 7 4!, the usual flue draft of the furnace then causing such dust to be drawn thereinto to up said flue andto the outside air. While I have shown the pipe 17 18-19 as made up of ordinary stove-pipe sections and elbows, it will be apparent that piping of any other description and of any desired cross section may be employed to accoinplish the purposes of the present invention. And although I have shown a preferred location for the opening for the pipe 17-18 19, namely, at the side of the hood 8 opposite the ash-receiving opening 11, said pipe opening may be located at any other portion of the hood.

In operation, a can 7, 'ofvany ordinary diameter, will be located alongside the furnace, in position to receive the pipe 17 18-19, the hood 8 will be positioned on the can 7, the flange 9 of said hood resting on the upper rim of the can. The end 15 of the pipe section will then be fitted over the flange 1 1- while the other extreme end of the pipe 17 18-19 will be placed on the lower edge of the opening 4 for the coaling door. Ashes from the ash-pit may then be shoveled through the opening 6 of the ash pit'and into the opening 11 in the hood 8. The draft in said hood caused by the direct draft from the furnace flue through the furnace and pipe 171819 will cause all dust arising from the ashes to be first drawn upward and circulated in the upper and central parts of the hood 8 and such parts thereof as do not fall back into the receptacle to be sucked from said hood into the pipe 17-1819 and the furnace flue to the outside of the furnace room, instead of spreading and settling in the room and on all articles therein, as has heretofore been the case.

As many changes could be made in the above construction and many apparently Widely different embodiments of my invention designed Without departing from the scope of the appended'claims, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative merely of an operative embodiment of my invention and not in a limiting sense.

Nhat I claim is an ash receptacle, comprising a removable hood therefor provided With an ash-receiving door, an outlet opening in said rota,

and dust-conducting pipe leading from said opening to the interior of the furnace, said hoodhaving a relatively large upper portion extending above said door and opening. providing a chamber adapted to cause the dust to circulate and collect in said upper portion and to fall in part into the receptacle, the residue being drawn into the dust-conducting pipe and out through the furnace flue.

A dust collector adapted for use with an hood having a cylindrical side wall with a closed top and provided with an ash-receiving door and outlet opening located oppo site thereto in said side Wall, and a dustconducting pipe leading from said opening to the interior of the furnace, said hood having a relatively large upper portion e1;- tendingabove said door and opening providing a chamber adapted to cause the dust to circulate and collect in said upper portion and to fall in part into the receptacle, the residue being drawn into the dust-conducting pipe and out through the furnace flue.
